One day at the end of May 1942, after the Jews had been kept for seven days in the ghetto, a detachment of Sipo and SD unit from Równe, assisted by Ukrainian auxiliary policemen, surrounded the ghetto and took about 400 of its inmates considered unfit for work, mainly women, little children and elderly people, outside the town, near the village of Hranówka, about 4 kilometers west of Kozin. Upon their arrival at the murder site, the victims had to strip naked and then, in small groups, were taken to the pit that had been prepared in advance by the Jews of Kozin. They had to lie inside the pit face down and then were shot to death in the back of the head with machine-guns by a detachment of the Sipo and SD from Rowne, with the assistance of the 1st company of the 33rd Reserve Police Battalion that had also arrived to the killing site. According to a ChGK document, little children were buried alive in the pit. This murder operation was carried out in coordination with the German agricultural administrator of Kozin De Von Beck Krause and the Ukrainian county chief Nikolay Serednitzkyi. One day in early October, 1942 members of the German Gendarmerie (German rural order police) and Ukrainian auxiliary police surrounded the ghetto and loaded its remaining inmates onto trucks that took them near the same village of Hranówka. Upon their arrival at the shooting site, the Jews were made to strip naked and forced into a pit where they were shot to death in the back of the head, with machine-guns by a Sipo and SD detachment from Równe.
